Well let's put it this way, i understand the ban... But our community made the BAN happen, take a close look...

We get 1.21 for MW3 fixed for CFW 3.55, what do those damn pesky script kiddies do?? Let's hack the ladder... let's hack the game.. let's just exploit this whole thing cause we are derp n00bz...

Infinity ward releases 1.22 and puts these kids a bit apart, but surely Sony was confronted to the Why does Blank Id's logging in PSN? now we have a bunch of n00bz cheating in our environment... And as this example other games have the same situation....

Kids Kids kids... If you have the pleasure of enjoying such a fine dandy app like FcKPSN and due to the wonder of some minds have the chance to play online again... DO NOT i repeat DO NOT Spit in the plate cheating/exploiting the game to the point that it becomes visible!!!

OFW users have their PS3 probably because they were tired of cheaters... and what to they get??? CFW users with the IQ of a freakin rock... cheating at the first time they get online again... So surely... not Sony's fault ... i guess you better blame it on our own "community", i for one... enjoyed playing again after all these months of ramadan... and didn't cheat/hack/exploit/glitched any of the games i played online... i just leveled normally like gamers do...

so.. we'll get another method and 3 months later we are shut down cause the kidz dosen't know how to "fair" use the perls that are given'

PS3 Custom Firmware (CFW) 3.55 on PlayStation Network (PSN) Guide

Following up on the previous FckPSN v0.9 updates, today Russian PlayStation 3 user BigFAN has made available a software package and guide on accessing PlayStation Network (PSN) while using PS3 Custom Firmware (CFW) 3.55 with details below.

To quote, roughly translated: Today, the user, who wished to remain anonymous, shared instructions for the return of PSN console with firmware 3.55 kastumnymi WARNING! INSTRUCTIONS NOT VERIFIED. All the action is at your OWN RISK! Let's proceed.

Require the availability of Java on your computer, you can download it at java.com Certificate from the archive should be copied to a folder PS3 / dev_blind / data / cert before original certificate. To this folder appeared on record in settings multiman 4.xx should put "Writing to dev_flash", as it is mounted dev_blind.

Next, you need a computer, a router, Sonya, combined into one network. In the settings pleysteyshona expose hands with a computer on the same subnet, the DNS IP write a computer in the network (not the Internet, and home address in lokalke). Run PS3DNS.exe of the pack, it will determine the IP company and ask if it is true, then the idea catches Sonya startup.

Let me remind you! Skype is hanging on by default 443 port, and can interfere with, change the port to it, or cancel the incoming to this port in the settings. Although you can turn off the stupid.

Run PS3DNS.exe, tuned Charlie (that it did not request every action allow all network via proxy -> access control settings 0.0.0.0 / 0). Turn on the PS3, log into PSN. PROFIT!

Shortly following, Asure also made available a FPSN Editable version / Mirror (simply unpack it and you'll see 3 directories (bin, lib, src) go to bin directory and execute go.bat)... stating the following:

Platform-version strings changed to have PS3_C (underscore-c is not present by default.. in 0.9)

bin\go.bat runs with spoofed consoleID

bin\go_nospoof_console_id.bat does not spoof consoleID at all.

Not at home, so I can't test if it works, but i see no reason why it won't. Note that the Russian version/charles version does not spoof consoleID. So if 'go' doesn't work, just ctrl-c and try the go_nospoof bat file. This is a drop-in for 0.9, you should have your certs etc. already setup on the PS3 side.. (see original readme from FPSN..)

Finally, from D3cH (via nextgenupdate.com/forums/playstation-3-exploits-hacks/593216-how-connect-psn-again.html) comes another guide below with a similar one also posted HERE:

v1.0: Fix spoofing (Thanks flys out to BigFAN from psjailbreak.ru and Asure from ps3hax for the informations.)
v0.9: Add support for 4.21 spoofing
v0.8: Re-add support for firmwares older than 3.55
v0.7: Add support for 4.11 spoofing
v0.6: Use an empty consoleid. Warning: be sure to get my 0.6 version
v0.5: Add support for firmwares older than 3.55
v0.4: Don't use PS3DNS anymore

Set the PS3's PRIMARY and SECONDARY DNS server to your PC's IP address

Reboot your PS3

Start FckPSN

Enjoy with PSN

Warnings

If you have followed the OLD guide you need to rename the original CA27.cer to CA27.cer.bak and (my) CA24.cer to CA27.cer and you have to restore the old CA24.cer, by renaming CA24.cer.bak to CA24.cer. This is needed since some games use the original CA24.cer

FAQs
